AUTOMATIC. OIL-CUP.

Specification of Letters Patent.

Patented July 31, 1906.

. 'To all whom it mag concern:

Be it known that I, JAMEs A. ANDERSON, a. citizen of the United States, residing in the borough. of Manhattan, city, county, and State ofNew York,.have invented certain new and useful Improvements in Automatic Oil-Cups, of which the following is a specification, reference being had therein to the accompanying drawings, in whichil ligure 1 is a longitudinal verticalsectional view. Fig. 2 is a detail sectional view SllOW- ing. a slightly-difierent form of the oil-feeding piston.

cups which are adapted to be connected to journals and tooperate to lubricate the shaft or axle mounted therein only when said shaft or axle is rotating. v

The invention is designed particularly for use in railway equipment to lubricate the caraxle journals, the lubricantapplying of the car will not affect means depending for its action upon the vibration of the j ournalebox.

One of the main objects of the invention is to provide such an oil-cup which will be reasonably sensitive to the vibrations of the j ournal-box, while at the same time acting to shut off the flow of oil to t when the caris at rest. 7

A further object of the invention is to provide the oil-cup with an inner supplemental oil-receptacle which is not in, communication with the main oil-receptacle except through its upper end and to provide means for feeding the oil from the main receptacle into the supplemental receptacle by capillary attrace journal tion, whereby the agitation of the oil in the main receptacle by reason of the movement the actual feeding of the oil to the. journal. This inner oil-receptacle is connected by suitable ports near the bottom of said receptacle. to an inner pistonchamber in which is mounted a suitable iston-cham ber is connected at its lower end by means of a suitable oil-passage to the car-journal, the piston by reason of its vibration during the movement of. the car serving to permit the oil to pass to the journal.

' Referring to the various parts by numeralsj, 1 designates an oil-cup which forms the main oil-receptacle. Centrally within this ositively cup is mounted a, supplemental cup 2, this latter cup forming a supplemental oilchamber. notches 2 in which a screw-driver may be inserted when it is desired to remove it from the main receptacle. nates below the upper end of the maln receptacle, and mounted in the center of the bottom of it is a tube 3, which is closed at its upper end and forms a piston-chamber 4, which is in communication with the supple- I mental oil-chamber at the lower end thereof through small ports 5. The bottom of the This invention relates to that class of oil,

the piston-chamberand to cover the outletport 6 to prevent the escape of oil through said port. While the iston 7 will be moved vertically and vibrated aterally in the piston-chamber by reason of the jolting of the car. This movement of the piston will cause it to force the oil through'the port 6 in the manner of a pump, the oil accumulating under the piston when it is moved upward or toward one side of the piston-chamberand being forced out through the port 6 when the piston is moved downward or toward the other side of the chamber. The ports 5 are formed in the pistoncasing below the upper end of the piston, said piston at all times extending over the inner ends .of said ports. The piston-chamber is of such length that thepiston cannot be lifted sufiiciently to wholly uncover the ports, thereby preventing an undue and unnecessary flow of oil to the journal should said piston be thrown to the top of its chamber byan unusual jolt of the car.-

In the form of piston shown in Fi' 2 the upper part 7 thereof fits snugly Wiflli iston-chamber, the lower part 7 thereof eing slightly reduced in diameter.

ports. By this means I provide two means for preventing the flow of oil to the carjournal when the car is at rest, the lower end of the piston closing the ports 6 and the part 7 of the piston closing the ports 5 It will be readily seen that the vibrations of the car will move the piston vertically sufficiently to bring the lower reduced part of thepiston opposite the ports 5, thus permitting the oil to flow to the bottom of the It is also clear that the downward movement of the piston will force the oil out through the port 6, said piston acting as a pump-piston.

To feed oil steadily from the main oil-receptacle 1 into the supplemental receptacle, two capillary feeding-wicks 8 are employed.

These wicks are arranged between the notches 2", and each consists of the part 8 which extends into the main receptacle, and the part 8 which extends into the supplemental receptacle. The part 8 extends to the bottom of the main receptacle, while the part 8 does not extend below the ports 5. By this means a steady and uniform supply of oil will be maintained in the inner receptacle and the agitation of the oil in the main .receptacle will not in the least affect the operation of the feeding means.

The upper end of the piston-chamber is closed, as before described, and is provided with the boss 9, which protects it. The said chamber is closed to prevent the accumulation of grit or foreign matter. It will also be readily seen that by feeding the oil through the capillary wick into the inner chamber the dust and dirt is prevented from flowing to the journal from the main oil-receptacle.

From the foregoing it is clear that I provide an extremely simple and eflicient oil-cup which will be automatic in its operation and by which a proper amount of oil will be fed to the car-journal during the rotation of the journal. The pump-like feed is particularly effective in supplying the proper amount of oil, while the piston at the same time forms a reliable means for effectively closing the outlet-port while the car is at rest.

Having thus-described my invention, what mess I claim as new, and desire to secure by Letters Patent, is-

1. An oil-cup comprising a main receptacle, a supplemental receptacle located within the main receptacle, means for feeding oil from the main receptacle into the sup leniental receptacle, an upright pisto11-c1a1nber formed within the supplemental receptacle, a piston therein having a straight lower end and slightly smaller in diameter than the diameter of the piston-chamber and adapted to be moved by the vibrations of the oil-cup, there being an outlet from said piston-chamber, said outlet being covered by the piston when said piston is at rest, the piston-chamber being provided with ports connecting it with the lower end of the supplemental chamber.

2. An oil-cup comprising a main receptacle, a supplemental receptacle located within the main receptacle, capillary means for feeding oil from the main receptacle into the supplemental receptacle, a piston-chamber located in the supplemental receptacle, said chamber being closed at its upper end and provided with oil-inlet ports near its lower end and with an oil-outlet port through its bottom, a piston in the piston chamber adapted to normally close the outlet-port from said chamber and to permit the feeding of oil therethrougli only during the oscillation of said piston.

3. A11 oil-cup com rising a main receptacle, a supplementa receptacle, capillary means for feeding oil from the main receptacle into the supplemental receptacle, a piston-chamber in the supplemental receptacle, a vertically-movable piston therein and adapted to close ports between the said piston-chamber and the supplemental oil-receptacle, the lower end of said piston being reduced in diameter, said reduced portion being normally below the oil-inlet ports into said piston-chamber.

In testimony whereof I hereunto allix my signature, in the presence of two witnesses, this 26th day of September, 1905.
